Heshun Industry Aluminium Profile
Pure aluminum low strength, its use is limited. However, adding a small amount of one or more alloying elements such as magnesium, silicon, manganese, copper, zinc, iron, chromium, titanium, etc., can be obtained with different properties of aluminum alloy. Aluminum and then by cold and heat treatment, and further to be hardened and hardened, its tensile strength greatly increased.
The standard electric potential of aluminum is -1.67 volts. Its chemical properties are very lively and easy to form a dense and dense oxide film with the oxygen in the air. Therefore, aluminum has good corrosion resistance in normal atmosphere and clean water. However, galvanic corrosion occurs when it comes into contact with steel or other metal materials, corrosion occurs in contact with alkaline materials such as concrete, cement mortar, lime and the like in a damp environment, and corrosion occurs when in contact with wood, soil or the like. Therefore, proper anticorrosive treatment is required.
Aluminum is different according to their production methods, divided into two major categories of aluminum casting and deformation of aluminum. The general construction of deformed aluminum alloy, used to roll into plates, foils, strips, extruded into rods, tubes or a variety of complex shapes profiles. Deformed aluminum according to their performance, different uses, is divided into rust-proof aluminum, duralumin, super-hard aluminum and special aluminum. General construction of industrial aluminum (L1 ~ L1), rust-proof aluminum (LF2, LF21, etc.) and forging aluminum (LD2) and so on.
The most important feature of aluminum and aluminum alloys is that their bulk density is about 1/3 of that of steel, while the specific strength (ratio of ultimate strength to specific gravity) can reach or exceed that of structural steel. Second, aluminum and aluminum alloys are easy to process into a variety of shapes and adapt to a wide range of joining processes, thereby providing favorable conditions for the building structure to adopt the most economical and rational cross-sectional form. Therefore, the use of aluminum alloy can not only greatly reduce the weight of the building, save material, but also reduce the components of the transport, installation workload, speed up the construction schedule. This is more significant for earthquake areas and mountainous and remote areas with limited traffic. Aluminum and aluminum alloy have beautiful color, good corrosion resistance, high light and heat reflectance, good sound absorption performance, and various colors can be obtained through chemical and electrochemical methods. Therefore, aluminum is widely used in industrial and civil buildings roofing, walls, windows and doors, skeletons, interior and exterior trim panels, ceilings, ceiling, railings handrails, interior furniture, store containers and construction templates.
The construction industry is one of the three major markets for aluminum products. Around 20% of the world's total aluminum output is used in the construction industry. In some industrialized countries, the construction industry uses more than 30% of the total aluminum output. Architectural aluminum products continue to update, color aluminum, aluminum composite panels, composite doors and windows, aluminum alloy panels and other innovative building products are also increasing year by year. China has made good use of aluminum alloy roofing, walls, doors and windows in industrial and civil buildings and gradually expanded its interior and exterior decoration and construction forms.
